摘要
Abstract
When the integrated circuits are tested by ATPG tools with the stuck-at model, the embedded memories in the integrated circuits design are taken as simple I/O models,ATPG tools fail to transfer the faults of combinational logics around the memories. Through the study of the DFT for SOC, the memory peripheral logics in a digital information security chip design were modified with the scanning principle. The design provided detectable paths for the shadow logics and improved the test coverage and fault coverage of the chip. The study analyzed the power and area and verified the effectiveness of the design.关键词
